Joseph Stella’s paintings sit quietly, unnoticed on the second floor of the Smithsonian American Art Museum (SAAM). People often pass them by, maybe one or two stopping to admire the vibrant color or dynamic movement, but otherwise Stella remains an obscure, unfamiliar name to the average American. What they don’t know about is his striking spectrum of work that evolved during the inter-war period in the 1920s and ‘30s or about his friendships with leading art figures of him time, such as Alfred Stieglitz, Walter Arensberg, Katherine Dreier, and Marcel Duchamp.
